Environmental Risk Assessment

Research has documented exposures and consequential environmental health effects of pesticides, PFAS, microplastics, and antibiotic resistance genes in environmental biota. Little is known, however, regarding such effects in white-tailed deer (Odocoileus virginianus).

The Columbia Environmental Research Center’s Per- and Polyfluoroalkyl Substance (PFAS) team conducts research focusing on the occurrence, fate, and toxicity of PFAS compounds in aquatic and terrestrial systems. Laboratory capabilities include dedicated analytical instrumentation and experimental facilities to allow USGS scientists to analyze a wide range of sample types including water, sediment...

Fluorochemicals are a class of structurally diverse synthetic compounds that contain a carbon-fluorine backbone.

In December 2020, our research group (as part of the Food Integrated Science Team) published a review of nitrapyrin costs and benefits in the journal Environmental Science & Technology.
